Definitions

  • the invention relates to a connection arrangement for connecting multi-core flat cables to a plug, which has a clamping area with a plug-in channel into which the multi-core, partly stripped flat cable can be inserted, the clamping area additionally being provided with cross channels opening into the latter, in the latter, in which clamping elements are arranged, which can be pressed into and fixed in the plug-in channel, so that the casing and the individual insulated conductors of the multi-core flat cable are jammed in the plug-in channel.
  • a plug-in connection for multi-core telephone cords is already known (DE-PS 24 32 122), in which the housing serving to accommodate the telephone cord is provided with a plug-in channel and transverse channels opening into these.
  • a clamping piece that is integrally connected to the housing via a film hinge is articulated on an inner wall.
  • the clamping pieces can each be pivoted with the aid of appropriate tools in such a way that the casing is jammed or the individual stripped insulated conductors of the multi-core telephone cord with respect to the housing.
  • the clamping pieces snap into place by partially protruding into the plug-in channel.
  • the film hinges do not guarantee the desired long-term jamming, because they may be damaged or tire with the tool.
  • the formation of the clamping pieces is difficult; the thin film hinges cannot be manufactured with the required accuracy in terms of their thickness.
  • the object of the present invention is to provide a connection arrangement with a more reliable and simple clamping for the covered and stripped areas of the individual wires of an electrical flat cable.
  • clamping elements arranged within the transverse channels are formed by the legs of a single U-shaped clamping bracket, the yoke preferably finding a stop surface in the fully pressed-in state on the connecting web present between the transverse channels.
  • both the sheathing and the individual conductors of the multi-core flat cable can be fixed in position by pressing in a single clamp.
  • the locking of the clamping bracket in the clamping area ensures that the clamping is effective in the desired manner over long periods of time.
  • the first embodiment of the connection arrangement according to the invention shown in FIG. 1 has a clamping area 1 which is arranged within the housing of an electrical plug and is preferably formed in one piece with the same.
  • This area 1 which can be produced by injection molding as usual, consists of an insulating material which can be elastically deformed to a small extent.
  • the clamping area 1 is provided with a plug-in channel 2, which has approximately rectangular entry and exit openings 2a, 2b. In its interior, the plug-in channel 2 has an enlarged area 2c and a narrowed area 2d, a transition area 2e with an inclined wall 2f being provided between these two areas 2c and 2d.
  • the plug-in channel 2 serves to accommodate a multi-core flat cable 3, which has a plurality of insulated conductors 4 which are surrounded by an outer sheath 5.
  • a multi-core flat cable 3 which has a plurality of insulated conductors 4 which are surrounded by an outer sheath 5.
  • the sheathing 5 is partially removed, so that sheathed and uncovered areas 3a and 3b of the multi-core flat cable 3 are formed.
  • the plug-in channel 2 is dimensioned with respect to the flat cable 3 to be clamped in such a way that the inner diameter of the expanded area 2c of the plug-in channel 2 is larger than the outer diameter of the flat cable 3 including the sheathing 5, while the inner diameter of the narrowed area 2d of the plug-in channel 2 is larger than the outer diameter of the conductor 4, however, is smaller than the outer diameter of the sheath 5.
  • the front edge of the sheathing 5 finds a stop on the inclined wall 2f, so that the front end of the flat cable 3 in the respective plug-in channel according to FIG. 1 2 is positioned.
  • the plug-in area 1 has two transverse channels 7 and 8 which are oriented perpendicular to the plug-in channel 2 and run parallel to one another and which open into the plug-in channel 2. These transverse channels 7, 8 are arranged such that in the inserted state of the flat cable 3, the transverse channel 7 abuts the covered area 3a and the transverse channel 8 encounters the uncovered area 3b of the flat cable 3.
  • a crossbar 9 is provided between the two transverse channels 7, 8, which has a lowered outer surface 9a relative to the outer surface la of the plug-in area 1, the importance of lowering the outer surface 9a of the connecting web 9 still being explained.
  • a U-shaped clamping bracket 10 preferably made of a resilient metal, can be used, which is preferably made by bending a corresponding metal strip.
  • the legs 11 and 12 of this clamping bracket 10 have at their free ends end sections 13, 14 which are barb-shaped toward one another or are bent inwards and upwards, the angle enclosed between the legs 11, 12 and end sections 13, 14 being approximately 60 ° is.
  • the legs 11, 12 and end sections 13, 14 of the clamping bracket 10 form relatively narrow clamping surfaces or clamping edges 16, 17, with which the covered and uncovered areas 3a, 3b of the flat cable 3 are clamped.
  • the leg 12 of the clamping bracket 10 is dimensioned somewhat longer than the leg 11, the length difference between the two legs 11, 12 corresponding approximately to the thickness of the sheath 5 of the flat cable 3.
  • the yoke 15 connecting the legs 11, 12 is so long that the two legs 11, 12 of the clamping bracket each abut on the inner wall of the transverse channels 7, 8 opposite the connecting web 9, while the end sections 13, 14 with their angled inwards and upwards Ends protrude so far in the direction of the connecting web 9 that the tips of the end sections are supported against the side surface of the connecting web and thus a jamming occurs even in the partially pressed-in position of the clamping bracket 10, as shown in FIG. 1.
  • FIGS. 1 and 2 The mode of operation of the described connection arrangement is shown in FIGS. 1 and 2.
  • the clamping bracket 10 As shown in FIG. 1, can be lost in the transverse channels 7 and 8 be pressed in, the inwardly projecting ends of the end sections 13 and 14 of the clamping bracket 10 can also cause an elastic indentation of the connecting web 9, so that the clamping bracket 10 is firmly seated.
  • the clamping bracket 10 is only pushed so far into the two transverse channels 7 and 8 that the plug-in channel 2 with its enlarged and narrowed areas 2c and 2d is kept free.
  • a modified multi-core flat cable 3 can be inserted into the plug-in channel 2 until the front edge of the sheathing 5 of the flat cable 3 strikes the inclined wall 2f provided in the area of the connecting web 9 of the clamping area 1. Then the yoke 15 of the clamping bracket 10 is pressed, whereby the clamping bracket 10 is pushed so far into the interior of the clamping area 1, if necessary, until the yoke 15 comes to rest on the outer surface 9a of the connecting web 9 between the transverse channels 7, 8. According to FIG. 2, the narrow clamping surfaces 16 and 17 provided on the front ends of the legs 11 and 12 are pressed against the covered and uncovered areas 3a, 3b of the flat cable 3, with a corresponding pinch of the flat cable 3.
  • the clamping bracket 10 is pushed into the transverse channels 7 and 8 until the inwardly projecting ends of the end sections 13 and 14 at least partially engage under the connecting web 9. This gripping under the connecting web 9 results in a latching, so that an excellent positional locking is achieved in this way.
  • the yoke 15 of the clamping bracket 10 lies below the outer surface la of the clamping area 1, so that the bracket is arranged to be protected from damage.
  • FIGS. 3 and 4 has many features of the embodiment according to FIGS. 1 and 2, which is expressed by the use of the same reference numerals.
  • the transverse channel 7 is made somewhat wider and there are also two tabs 18, 19 which protrude into the two transverse channels 7, 8 on the lower edge of the transverse channels 7, 8, on the side opposite the connecting web 9.
  • a U-shaped clamping bracket 10 'made of a resilient plastic is used.
  • the two legs 11 ', 12' of the clamping bracket 10 ' can have tooth-like projections 20, 21, the function of which will be described below.
  • the legs 11 ', 12' are provided at their free ends with end portions 13 ', 14' which protrude outward like barbs.
  • end portions 13 ', 14' with their outwardly angled ends protrude so far in the direction pointing from the connecting web 9 that they rest in the partially pressed-in state of the clamping bracket 10 on the projections 20, 21, while the legs may be clamping on the connecting web issue.
